Description

Technical Field

[0001] The invention relates to the technical field of water washing machines, and in particular to a constant tension water washing machine, a method for reducing the amount of liquid carried, and a continuous dyeing method. Background Art

[0002] Before dyeing, the fabric needs to be washed to remove oil and desizing. The washing process is usually carried out in a traditional open-width continuous washing machine. The washing process of the traditional washing machine is very long. Usually, the fabric flows in the washing tank for about 300 meters. This is to ensure that the fabric has sufficient time to contact with water and various additives while being processed quickly, so that the impurities such as slurry or grease adhering to the fabric can be fully swollen and then washed away. The traditional washing machine is arranged in a linear manner or the fabric runs in a serpentine shape in the washing tank, but the equipment still needs to be about 50-100 meters long to meet the requirements of use.

[0003] In addition, the liquid carrying rate (ratio of liquid carrying amount to cloth weight) of the cloth output after washing by the traditional open-width continuous washing machine is more than 60%, resulting in high energy consumption for subsequent drying, and there are problems such as bulky equipment, high energy consumption, and high water consumption.

[0004] Due to the high liquid carryover rate after traditional water washing, it is not suitable for direct padding dyeing treatment. Otherwise, the moisture carried by the cloth after washing will be brought into the dyeing solution during the padding process, and the amount of dyeing solution obtained on the cloth is too small. Therefore, in the traditional padding dyeing process, the degreasing or desizing step must be carried out separately from the padding step, and the drying operation must be carried out after water washing. The padding operation can only be carried out after the liquid carryover rate of the cloth is reduced, so the energy consumption is high and the efficiency is low.

[0005] In the conventional rolling mill, during the continuous rolling process, since the path between the rollers and the support wheels is fixed and the cloth is inevitably stretched during operation, the tension in the process cannot be kept constant, causing the cloth between the rollers to loosen or even accumulate, affecting the continuous operation.

[0006] In order to solve the above technical problems, finding a small, low energy consumption, low water consumption, and efficient washing machine and washing and dyeing machine has become an important topic studied by technical personnel in this field. Summary of the invention

[0061] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0062] The embodiment of the present invention provides a constant tension washing machine, which at least includes a cloth sending device 1, a frame 2, a washing tank 3, a first pressing device 4, and a second pressing device 5; the first pressing device 4 at least includes a first pressing roller 15 and a second pressing roller 16 that are mutually pressed;

[0063] The washing tank 3 is provided with a plurality of upper wheel groups 11 and lower wheel groups 12 in sequence, and the plurality of upper wheel groups 11 and lower wheel groups 12 are arranged alternately up and down;

[0064] The water washing tank 3 has an input end and an output end, the first pressing device 4 is arranged between the cloth sending device 1 and the input end of the water washing tank 3, and the second pressing device 5 is arranged at the output end of the water washing tank 3;

[0065] During operation, the dry fabric is output from the fabric delivery device 1 and enters between the first pressing roller 15 and the second pressing roller 16, and the dry fabric is pressed;

[0066] The dry cloth outputted from between the first pressing roller 15 and the second pressing roller 16 enters from the input end of the washing tank 3, and passes through the upper wheel group 11 and the lower wheel group 12 in sequence, so as to cross-convey the cloth to be washed in the washing tank 3;

[0067] The washed cloth is output from the output end of the washing tank 3 and enters the second pressing device 5 at the corresponding position. The cloth output from the second pressing device 5 carries a certain amount of solution.

[0068] The cloth carrying a certain amount of solution enters the first pressing device 4 again, is pressed by the first pressing roller 15 and the second pressing roller 16, and then overlaps with the dry cloth entering the first pressing device 4.

[0069] The working principle of the present invention is as follows: since the cloth that enters the first pressing device 4 for the first time is dry cloth, the cloth carrying a certain amount of solution is overlapped with the dry cloth, and the certain amount of solution carried by the cloth that enters the first pressing device 4 for the second time is redistributed, and a part of the solution is distributed to the cloth that enters the first pressing device 4 for the first time. Finally, the liquid amount of the cloth output from the first pressing device 4 is reduced, thereby reducing the energy consumption in the next drying process.

[0070] The upper wheel group 11 at least includes an upper first row of support wheel groups, an upper second row of support wheel groups to an upper Nth row of support wheel groups, which are arranged in sequence from top to bottom. Each row of the upper support wheel groups is provided with a plurality of support wheels in sequence from front to back in the horizontal direction. In the vertical direction, the support wheels corresponding to the upper first row of support wheel groups, the upper second row of support wheel groups to the upper Nth row of support wheel groups are arranged in rows up and down, forming an upper first row, an upper second row to an upper Nth row of support wheel groups in sequence from front to back.

[0071] The lower wheel group 12 at least includes a lower first row of support wheel groups, a lower second row of support wheel groups to a lower Nth row of support wheel groups which are arranged in sequence from top to bottom, and each row of the lower support wheel groups is provided with a plurality of support wheels in sequence from front to back in the horizontal direction, and in the vertical direction, the support wheels corresponding to the lower first row of support wheel groups, the lower second row of support wheel groups to the lower Nth row of support wheel groups are arranged in rows up and down, forming the lower first row, the lower second row to the lower Nth row of support wheel groups in sequence from front to back.

[0073] The cloth output from between the first pressing roller 15 and the second pressing roller 16 is guided by the guide wheel, enters the washing tank 3 from the entrance of the washing tank 3, passes through the N-row support wheel groups of each lower layer and the N-row support wheel groups of each upper layer in turn, and then turns back from the N-row support wheel groups of the upper layer to enter the second-row support wheel groups of each lower layer and the second-row support wheel groups of each upper layer, and then turns back from the second-row support wheel groups of the upper layer to enter the support wheels of the first-row support wheel groups of each lower layer and the first-row support wheel groups of each upper layer, and enters the second pressing device 5 at the upper outlet of the washing tank 3 at the corresponding position from the support wheels of the first-row support wheel groups of the lower layer or the first-row support wheel groups of the upper layer.

[0074] In this embodiment, the washing machine further includes a cloth tension control device, which at least includes a cloth storage tank 6 device and / or a sliding friction roller device.

[0075] In this embodiment, there are multiple water washing tanks 3, and the output end of each water washing tank 3 is respectively provided with at least one second pressing device 5; the first end of each water washing tank 3 connected in sequence is the input end, and the second end is the output end;

[0076] The liquid level of each washing tank 3 gradually rises from front to back, forming a liquid level difference, and clean water is added to the last washing tank 3, or sprayed from the water spray pipe to the cloth surface in front of the last second pressing device 5, flows into the last washing tank 3, and then flows forward one by one, the sewage leaves the washing tank 3 from the first washing tank 3, and the cloth runs countercurrently from front to back. After leaving the washing tank 3 and the last second pressing device 5, the cloth becomes clean cloth.

[0077] The second pressing device 5 located at the output end is integrally arranged with the first pressing device 4 and arranged front and back. The second pressing device 5 includes a second pressing roller 16 and a fourth pressing roller 14 for pressing. After the cloth is output from the cloth sending device 1, it enters between the first pressing roller 15 and the second pressing roller 16 and is pressed for the first time; after being washed in the washing tank 3, it enters between the second pressing roller 16 and the fourth pressing roller 14 and is pressed for the second time; the cloth enters between the second pressing roller 16 and the first pressing roller 15 again and is pressed for the third time.

[0078] In this embodiment, the water washing tank 3 is a large water tank, and the water washing tank 3 is divided into a plurality of continuously arranged small water washing tanks 3 by partitions, and each small water washing tank 3 is provided with a corresponding upper wheel group 11 and a lower wheel group 12, and a corresponding second pressing device 5; a cloth storage tank 6 is also provided between the cloth sending device 1 and the input end of the water washing tank 3;

[0079] A vacuum dehydration device 8 and / or an air knife device 9 is also provided between the first pressing device 4 and the second pressing device 5; the air knife device 9 comprises a high-pressure blower, an air duct, and an air knife connected in sequence, the air knife is arranged toward the cloth and close to the cloth, and is arranged opposite to the suction port of the suction pipe of the vacuum dehydration device 8;

[0080] The vacuum dehydration device 8 includes a vacuum pump, a suction pipe connected to the vacuum pump, and a second conveyor belt device. The second conveyor belt device includes a second conveyor belt and two second conveyor belt support wheels. The second conveyor belt is a mesh conveyor belt. The suction pipe is arranged between the two second conveyor belt support wheels and is located inside the second conveyor belt. The working surface of the second conveyor belt is in contact with the cloth. The wind knife is arranged toward the cloth and close to the cloth, and is arranged opposite to the suction port of the suction pipe of the vacuum dehydration device 8.

[0081] The cloth passes between the wind knife and the suction port of the suction pipe, and the excess moisture carried by the cloth is blown away from the cloth by the wind knife, and at the same time is sucked into the suction pipe by the suction port of the suction pipe, thereby reducing the amount of liquid carried by the cloth when it enters the first pressing device 4 for the second time. After the cloth enters the first pressing device 4 for the second time, it is mixed with the dry cloth that enters the first pressing device 4 for the first time, thereby further reducing the amount of liquid carried by the cloth.

[0082] In this embodiment, there are multiple water washing tanks 3, and the output end of each water washing tank 3 is respectively provided with at least one second pressing device 5; the first end of each water washing tank 3 connected in sequence is the input end, and the second end is the output end;

[0083] The first pressing device 4 at least includes a first pressing roller A, a first pressing roller B, a second pressing roller C, and a second pressing roller D which are arranged in sequence. After the cloth is output from the cloth sending device 1, it enters between the first pressing roller B and the second pressing roller C and is pressed for the first time; after being washed in the washing tank 3, it is output from the second pressing device 5 located at the output end, and then enters between the second pressing roller C and the second pressing roller D and is pressed for the second time;

[0084] The first pressing roller A and the second pressing roller D are steel rods or rubber-coated rollers, the first pressing roller B and the second pressing roller C are water-absorbing rollers, the axis of the water-absorbing roller is a steel core shaft, and the outer circle of the axis is covered or sleeved with an elastic water-absorbing layer, and the elastic water-absorbing layer is one or more of Teflon, graphene, aramid, paper, cotton, polyester fiber, and microporous sponge rubber.

[0085] Since the rigidity of the suction roller is relatively low, a high-strength steel rod or rubber-coated roller is arranged on the outside of the two suction rollers to press the suction rollers front and back. The pressure is transmitted to the suction roller from the roller surface of the front and rear steel rods or rubber-coated rollers. The axis of the suction roller is less affected by the pressure, and the suction roller is not easily deformed. The pressure of the pressing seam between the two suction rollers is relatively uniform. After the cloth passes between the two suction rollers and is pressed, the amount of liquid on the left, middle and right sides of the cloth is more uniform.

[0086] The cloth carrying a certain amount of moisture enters between the two absorbent rollers. Since there are gaps on the surface of the absorbent rollers and they are absorbent, in the early stage of the pressing process, that is, before the pressing point of the two absorbent rollers, the elastic absorbent layer is subjected to positive pressure, the gaps in the elastic absorbent layer are squeezed, the gaps are reduced, and the excess moisture carried by the cloth is squeezed out. After passing the pressing point of the two absorbent rollers, the elasticity of the elastic absorbent layer is released, and the gaps inside the elastic absorbent layer are instantly subjected to negative pressure. This negative pressure will absorb the cloth that has just been squeezed, thereby absorbing part of the moisture still carried on the surface of the cloth into the gaps in the elastic absorbent layer, further reducing the amount of liquid carried by the cloth.

[0087] Since the cloth between the first pressing roller B and the second pressing roller C is unwashed cloth and is dry cloth without water, after the dry cloth without water is pressed by the first pressing roller B and the second pressing roller C, part of the moisture in the gaps of the elastic water-absorbing layer on the surface of the second pressing roller C is taken away, thereby reducing the moisture content in the gaps of the elastic water-absorbing layer on the surface of the second pressing roller C.

[0088] Since the second pressing roller C is in continuous operation, when it is pressed with the second pressing roller D again, the second pressing roller C will absorb part of the moisture from the cloth between the second pressing rollers D and C, so that the quantitative moisture carried by the cloth is reduced, and then the above process is continuously repeated, so that the liquid amount of the cloth finally output is reduced.

[0089] The process of dry / wet mixed rolling to reduce the amount of liquid is that the dry cloth and the wet cloth pass through the same rolling point at the same time, and the moisture carried by the wet cloth is redistributed into the two layers of cloth. In this process, since the two layers of cloth are in direct contact, for cloth with a rougher surface, the textures of the two layers of cloth will be imprinted on each other, resulting in the superposition of the two cloth texture patterns, which will cause the liquid amount of the convex and concave parts of the cloth texture to be inconsistent, and in the subsequent dyeing process, the superposition of the two cloth texture patterns will appear, affecting the cloth effect.

[0090] The process of the water-absorbing roller rotating to absorb water and reduce the amount of liquid carried is an indirect process. The two layers of cloth are not directly pressed together, and the texture of the water-absorbing roller is fine and will not be imprinted on the surface of the cloth. In the subsequent dyeing process, the cloth will appear with an overlapping pattern of two cloth surface texture patterns, and the cloth surface effect is better.

[0091] Since the cloth before entering the two water-absorbing rollers needs to be cloth with a certain amount of liquid, the first pressing device 4 must be arranged after the last second pressing device 5, so that a lower amount of liquid can be obtained. Therefore, the first pressing device 4 is arranged after the second pressing device 5 in the present invention, which is not a simple superposition of two pressing devices. The simple superposition of two pressing devices cannot achieve the function of the first pressing device 4 arranged after the second pressing device 5 of the present invention.

[0092] In one example, the first pressing roller A and the first pressing roller B are the same pressing roller, namely the first pressing roller. In this case, the first pressing roller needs to have good rigidity and strength, otherwise the liquid amounts on the left, middle and right sides of the product will be inconsistent.

[0093] In one example, the first pressing roller A and the second pressing roller D are steel rods or rubber-coated rollers, the first pressing roller B and the second pressing roller C are water-absorbing rollers, the axis of the water-absorbing roller is a steel core shaft, and the outer circle of the axis is covered or sleeved with an elastic water-absorbing layer, and the elastic water-absorbing layer is one or more of Teflon, graphene, aramid, paper, cotton, polyester fiber, and microporous sponge rubber.

[0094] In one example, the outlet of the washing tank 3 is connected to a second pressing device 5, and the second pressing device 5 is one or more of a fiber roller pressing device, a vacuum negative pressure adsorption device, and a positive pressure blowing device.

[0095] The outlet of the washing tank 3 is connected with a washing and deliquescence device, which is a second pressing device 5 , and includes a fiber roller pressing device and / or a vacuum negative pressure adsorption device and / or an air knife device 9 .

[0096] In this embodiment, the first pressing device 4 and the second pressing device 5 are arranged front and back, and the first pressing device 4 and the second pressing device 5 are arranged integrally, the first pressing device 4 and the second pressing device 5 share the same power device, the first pressing roller, the second pressing roller, the third pressing roller 13, and the fourth pressing roller 14 are arranged in sequence, at least the second pressing roller and the third pressing roller 13 are pressing rollers with elastic water-absorbing layers on the surface, and the elastic water-absorbing layers are fiber layers or rubber-plastic elastomers with water-absorbing micropores, and the fiber layers are one or more of Teflon, graphene, aramid, paper, cotton, polyester fiber, etc., and the first pressing roller and the fourth pressing roller 14 are steel rods or rubber-coated rollers or pressing rollers with elastic water-absorbing layers on the surface;

[0097] A first guide wheel is arranged below between the first pressing roller and the second pressing roller, and the first guide wheel guides the cloth from the cloth sending device 1 to enter between the first pressing roller and the second pressing roller. A second guide wheel is arranged above between the first pressing roller and the second pressing roller, and the second guide wheel guides the cloth from the output ends of the first pressing roller and the second pressing roller to enter the entrance of the washing tank 3;

[0098] A third guide wheel is arranged below the third pressing roller 13 and the fourth pressing roller 14, and the third guide wheel guides the cloth to enter between the third pressing roller 13 and the fourth pressing roller 14 from the outlet of the washing tank 3. A fourth guide wheel is arranged below between the second pressing roller 13 and the third pressing roller 13, and the fourth guide wheel guides the cloth to be output from below between the second pressing roller 13 and the third pressing roller 13.

[0099] After being output from the cloth sending device 1, the cloth is guided by the first guide wheel and enters between the first pressing roller and the second pressing roller, is pressed for the first time, and then is guided by the second guide wheel to enter the washing tank 3 from the entrance of the washing tank 3. After being guided, pulled and pressed by a plurality of supporting wheels and a plurality of second pressing devices 5, it is output from the output end of the washing tank 3, guided by the third guide wheel and enters between the fourth pressing roller 14 and the third pressing roller 13, is pressed for the second time, and the excess water carried by the cloth is squeezed out, so that the cloth obtains a large amount of liquid.

[0100] Since at least the third pressing roller 13 is a pressing roller with an elastic water-absorbing layer on its surface, the cloth carrying excess water enters between the fourth pressing roller 14 and the third pressing roller 13. Since the surface of the third pressing roller 13 has gaps and is water-absorbent, in the early stage of the pressing process between the fourth pressing roller 14 and the third pressing roller 13, that is, before the pressing point of the fourth pressing roller 14 and the third pressing roller 13, the elastic water-absorbing layer of the third pressing roller 13 is subjected to positive pressure, the gaps in the elastic water-absorbing layer are squeezed, the gaps are reduced, and the excess water carried by the cloth is squeezed out; after passing the pressing point of the fourth pressing roller 14 and the third pressing roller 13, the elasticity of the elastic water-absorbing layer is released, and the gaps inside the elastic water-absorbing layer are instantly subjected to negative pressure, which adsorbs the cloth that has just been squeezed, thereby absorbing part of the water still carried on the surface of the cloth into the gaps in the elastic water-absorbing layer, and the cloth obtains a lower and quantitative amount of liquid.

[0101] As the third pressing roller 13 rotates, the cloth enters between the third pressing roller 13 and the second pressing roller and is pressed for the third time. Since the second pressing roller and the third pressing roller 13 are both pressing rollers with elastic water-absorbing layers on their surfaces, the cloth carrying a certain amount of water enters between the second pressing roller and the third pressing roller 13. Since there are gaps on the surfaces of the second pressing roller and the third pressing roller 13 and they are water-absorbent, in the early stage of the pressing process of the second pressing roller and the third pressing roller 13, that is, before the pressing point of the second pressing roller and the third pressing roller 13, the elastic water-absorbing layers of the second pressing roller and the third pressing roller 13 are subjected to positive pressure, the gaps in the elastic water-absorbing layers are squeezed, the gaps are reduced, and part of the water carried by the cloth is squeezed out. After passing the pressing point of the second pressing roller and the third pressing roller 13, the elasticity of the elastic water-absorbing layer is released, and the gaps inside the elastic water-absorbing layer are instantly subjected to negative pressure. This negative pressure will absorb the cloth that has just been pressed, thereby absorbing part of the water still carried on the surface of the cloth into the gaps in the elastic water-absorbing layer, further reducing the amount of liquid carried by the cloth.

[0102] At the same time, since the cloth between the first pressing roller and the second pressing roller is unwashed cloth and is dry cloth without water, after the dry cloth without water is pressed by the first pressing roller and the second pressing roller, part of the moisture in the gaps of the elastic water-absorbing layer on the surface of the second pressing roller is taken away, thereby reducing the moisture content in the gaps of the elastic water-absorbing layer on the surface of the second pressing roller.

[0103] Since the second pressing roller is in continuous operation, when the second pressing roller is pressed together with the third pressing roller 13 again, the second pressing roller will absorb part of the moisture from the cloth between the third pressing roller 13 and the second pressing roller C, so that the quantitative moisture carried by the cloth is reduced. Since the operation is continuous, the above process is repeated continuously, so that the liquid amount of the cloth finally output is minimized.

[0104] The cloth is guided by the fourth guide wheel and outputted from the woven cloth drying-free washing machine of the present invention.

[0105] In this embodiment, the first pressing device 4 and the second pressing device 5 are arranged in front and behind each other, and the second pressing device includes a third pressing roller 13 and a fourth pressing roller 14.

[0106] The first pressing device 4 and the second pressing device 5 are integrally arranged, and the first pressing device 4 and the second pressing device 5 share the same power device. The first pressing roller, the second pressing roller, the third pressing roller 13, and the fourth pressing roller 14 are arranged in sequence. The first pressing roller includes a first pressing roller A and a first pressing roller B. The first pressing roller A and the first pressing roller B are arranged on the outer circle of the second pressing roller, and are pressed and arranged in sequence with the second pressing roller; at least the second pressing roller and the third pressing roller 13 are pressing rollers with elastic water-absorbing layers on the surface, and the elastic water-absorbing layers are fiber layers or rubber-plastic elastomers with water-absorbing micropores, and the fiber layers are one or more of Teflon, graphene, aramid, paper, cotton, polyester fiber, etc. The first pressing roller and the fourth pressing roller 14 are steel rods or rubber-coated rollers or pressing rollers with elastic water-absorbing layers on the surface;

[0107] A first guide wheel is arranged beside the first pressing roller A, and the first guide wheel guides the cloth from the cloth sending device 1 to enter between the first pressing roller A and the second pressing roller, and then enter between the first pressing roller B and the second pressing roller. A second guide wheel is arranged beside the first pressing roller B, and the second guide wheel guides the cloth from the output ends of the first pressing roller B and the second pressing roller to the entrance of the washing tank 3;

[0108] A third guide wheel is arranged below between the third pressing roller 13 and the fourth pressing roller 14, and the third guide wheel guides the cloth to enter between the third pressing roller 13 and the fourth pressing roller 14 from the outlet of the washing tank 3. A fourth guide wheel is arranged above between the second pressing roller 13 and the third pressing roller 13, and the fourth guide wheel guides the cloth to be output from the output end between the second pressing roller 13 and the third pressing roller 13.

[0109] In one example, the first pressing roller or / and the second pressing roller or / and the third pressing roller 13 or / and the fourth pressing roller 14 are covered or sleeved with an elastic water-absorbing layer, the elastic water-absorbing layer is a fiber layer or an elastomer provided with water-absorbing micropores, and the fiber layer is one or more of Teflon, graphene, aramid, paper, cotton, polyester fiber, etc. By providing the elastic water-absorbing layer, the amount of liquid carried can be further reduced.

[0110] In one example, the first pressing roller or / and the second pressing roller or / and the third pressing roller 13 or / and the fourth pressing roller 14 are rubber rollers with micropores on the surface, such as so-called sponge rollers, or concave micropores are formed on the surface of traditional rubber rollers by needle punching or mold embossing. In the front stage of lamination, the pressing rollers are compressed and squeeze out most of the moisture carried by the cloth. At the moment after the cloth passes through the nip, the pressing rollers rebound and a vacuum is formed inside the micropores of the pressing rollers, which absorbs part of the moisture remaining on the cloth into the micropores, thereby reducing the final liquid content of the cloth.

[0111] In one example, the first pressing roller and / or the second pressing roller and / or the third pressing roller 13 and / or the fourth pressing roller 14 are vacuum water-absorbing rollers, that is, the interiors of the first pressing roller and / or the second pressing roller and / or the third pressing roller 13 and / or the fourth pressing roller 14 are connected to the vacuum or negative pressure device through the center holes at the ends of their shafts, and the surfaces of the rollers are provided with micropores connected to the interior, and the vacuum or negative pressure washes away excess water through the micropores, thereby further reducing the amount of liquid carried.

[0112] In this embodiment, the cloth tension control device is a sliding friction roller device, the second roller is rotatably connected to the frame 2, the first roller is arranged between the first guide wheel and the second guide wheel, and the first roller and the second roller are arranged with an adjustable distance. In the working state, the cloth between the first guide wheel and the second guide wheel is wrapped around the surface of the second roller, and the distance between the first guide wheel and the second roller, as well as the wrap angle between the cloth and the second roller can be changed by adjusting the distance between the first roller and the second roller.

[0113] In this embodiment, there are multiple water washing tanks 3, and the output end of each water washing tank 3 is respectively provided with at least one second pressing device 5; the first end of each water washing tank 3 connected in sequence is the input end, and the second end is the output end;

[0114] The second rolling device 5 located at the output end is arranged above the first rolling device 4, and the third pressing roller 13 and the fourth pressing roller 14 are respectively arranged above and below the first pressing roller and the second pressing roller of the first rolling device 4, and the speed of the last second rolling device 5 is set to be not lower than the speed of the first rolling device 4.

[0115] By changing the wrap angle between the cloth between the first guide wheel and the second guide wheel and the second pressing roller, the contact area between the cloth and the second pressing roller is adjusted. Increasing the contact area can transfer more of the solution carried by the second pressing roller to the cloth, which can better reduce the amount of liquid carried.

[0116] At the same time, since the cloth needs to be driven by the pressure rollers to run, the cloth will inevitably be stretched and lengthened during the operation, and the path of the cloth between the pressure rollers and the guide wheels is fixed. If the pressure rollers are in a tight state, long-term operation will cause the cloth between the pressure rollers to be stretched, loose or even piled up, affecting the operation. In particular, after the cloth is output from between the first pressure roller and the second pressure roller, it passes through several guide wheels, support wheels and pressing devices. The travel path of the cloth is long, and the cloth is bound to be stretched to a certain extent, affecting normal operation.

[0117] To solve this problem, the present invention sets the first pressing roller and the second pressing roller with an adjustable distance, that is, the first pressing roller and the second pressing roller may not be in a pressed state, and the cloth between the first pressing roller and the second pressing roller is only covered on the surface of the second pressing roller, and can slide relative to the second pressing roller (commonly known as slipping), so that the running speed of the cloth between the first pressing roller and the second pressing roller is not higher than the traction speed of the first second pressing device 5 in front, and the cloth will not be loosened or accumulated after being output from between the first pressing roller and the second pressing roller to the first second pressing device 5, thereby ensuring normal operation.

[0118] In this embodiment, the cloth tension control device includes a cloth storage tank 6, and a cloth storage tank 6 is further provided between the output end of the first pressing device 4 and the inlet of the washing tank 3, and the inlet and outlet ends of the cloth storage tank 6 are connected to the frame 2;

[0119] A first conveyor belt device 7 is also provided between the output end of the first pressing device 4 and the entrance of the fabric storage tank 6, or / and between the fabric storage tank 6 and the entrance of the washing tank 3. The first conveyor belt device 7 is connected to the frame 2 and includes a power roller, a support wheel, and a conveyor belt.

[0120] The cloth output from the first pressing device 4 after the first pressing is transported by the first conveyor belt device 7 and runs into the washing tank 3.

[0121] Since the washing path is long and the cloth passes through multiple guide wheels and pressing devices, the cloth will inevitably be stretched and lengthened during the washing process. The path of the cloth from the cloth sending device 1, the washing tank 3, the second pressing device 5, and the first pressing device 4 is fixed. Long-term operation will cause the stretched cloth to accumulate in the washing tank 3 or in front of the pressing device, affecting the operation.

[0122] The second pressing device 5 and the first pressing device 4 are arranged correspondingly up and down. After the cloth is output from the second pressing device 5, it can fall directly between the first pressing roller and the second pressing roller of the first pressing device 4 under the action of its own gravity. Since the speed of the last second pressing device 5 is set to be not lower than the speed of the first pressing device 4, the cloth falling into the first pressing device 4 will be taken away and output along with the operation of the first pressing device 4, so that no accumulation will occur.

[0123] In order to solve the problem of cloth accumulation due to excessive stretching of cloth with strong elasticity, the present invention arranges a cloth storage tank 6 between the output end of the first pressing device 4 and the entrance of the washing tank 3. After the cloth is pressed and output by the first pressing device 4 for the first time, it passes through the cloth storage tank 6 and then enters the washing tank 3. A tension device is arranged before the second pressing device 5. Under the control of the tension device, the cloth runs in a stable tension state between the washing tank 3 and the second pressing device 5. The excess cloth generated by the stretching of the cloth is continuously stored in the cloth storage tank 6, which will not affect the normal operation of production.

[0124] At the same time, in order to prevent the cloth from being stretched as much as possible, a first conveyor belt device 7 is also provided. The cloth output from the first pressing device 4 after the first pressing is conveyed by the first conveyor belt device 7 and runs into the washing tank 3.

[0125] Furthermore, all or part of the guide wheels in the washing tank 3 are connected to the power device, and the movement of the cloth in the washing tank 3 is driven by power, which can further reduce the stretching amount of the cloth during the operation.

[0126] The present invention ensures continuous and stable production of cloth through the multi-faceted settings of the cloth storage trough 6 device, the first conveyor belt device 7, the tension control device, the power device, and the positional relationship between the first pressing device 4 and the second pressing device 5.

[0127] In this embodiment, a plasma treatment device is further provided in front of the washing tank 3 or / and behind the washing machine. The plasma treatment device includes an electrically connected mainframe, a transformer, and a discharge frame. The electrode of the discharge frame is a ceramic rod and is equipped with a treatment roller. The treatment roller is a rubber-coated roller. The electrode is arranged toward the treatment roller. An ozone exhaust hood and a heat dissipation fan are also provided above the discharge frame. Each treatment roller is equipped with a fan and an ozone exhaust hood. The heat dissipation fan is connected to an air duct, and the other end of the air duct is connected to the washing tank 3.

[0128] The cloth passes between the processing roller and the electrode, and the plasma acts on the surface of the cloth to etch the cloth.

[0129] In one example, the plasma device includes 4 10KW main machines and 4 transformers. The output voltage of the transformer is 15KV, the operating frequency is 19KHZ, the efficiency of the whole machine is greater than 95%, and the ambient temperature is between -10℃ and +40℃. The main circuit inverter part adopts IGBT power module and special drive circuit, fixed circuit operating frequency, and changes the output power by adjusting the pulse width. It has a soft start function to prevent large current from polluting the power grid and damaging the equipment. When the ambient humidity is high, it does not affect the normal start and operation of the equipment. It is also equipped with stall protection, electrode opening protection, load breakdown and spark protection, overheating protection, overcurrent protection and other functions. It is also equipped with a double-sided discharge rack. The electrodes of the discharge rack are square ceramic rods, 12 on one side, and 24 on a total of sides. It is also equipped with 4 processing rollers, which are rubber-coated. The electrode rack is equipped with an ozone exhaust cover; at the same time, it is also equipped with 4 2.2KW fans for ozone exhaust and heat dissipation, and each fan is connected to a processing roller. The system is controlled by PLC operation.

[0130] Since the first pressing device 4, the second pressing device 5, the vacuum dehydration device 8 and the air knife device 9 are non-drying liquid removal devices, it is difficult to fully remove the moisture carried by the cloth during the washing process, and the cloth still carries a certain amount of moisture. The plasma device arranged at the rear of the washing machine has a heating function, which can further decompose the slurry or grease remaining on the cloth surface while further removing moisture, so that the liquid carrying rate of the output cloth is further reduced.

[0131] In one example, a plasma treatment device is provided before or / and after the water washing step, and a heating treatment process is provided in front of or / and behind the plasma treatment device to decompose and volatilize impurities on the surface of the fabric at high temperature, thereby shortening the plasma treatment time and saving equipment costs.

[0132] In one example, a plasma treatment step is also provided before the water washing step. The plasma can decompose the slurry and grease on the surface of the fabric. The fabric is further degreased and desizing by the water washing step, and the particles and impurities left by the plasma treatment are cleaned. Ultrasonic cleaning is performed while washing. After the water washing is completed, the fabric is subjected to liquid removal treatment by the first pressing device 4, the second pressing device 5, the vacuum dehydration device 8 and the air knife device 9, and then subjected to plasma treatment again to further reduce the amount of liquid.

[0133] In one example, the washing tank 3 is a large washing tank 3, which is divided into several small washing tanks 3 by a stainless steel shield. The outer wall and the bottom of the large washing tank 3 are provided with an ultrasonic oscillation device 10, and an ultrasonic oscillation device 10 is also provided between two adjacent small washing tanks 3. The ultrasonic oscillation device 10 provided between two adjacent washing tanks 3 includes two groups of ultrasonic vibrators provided back to back. The ultrasonic vibrators are immersed in the washing tank 3 and provided in the stainless steel shield. They are isolated from the water in the tank by the stainless steel shield. The vibration end of the ultrasonic vibrator is connected to the wall of the stainless steel shield. The two groups of ultrasonic vibrators provided back to back are respectively provided toward the fabrics in the two adjacent washing tanks 3.

[0134] Furthermore, the ultrasonic oscillation device 10 includes an ultrasonic generator, an amp, a transducer and a vibrator; the amp is electrically connected to the ultrasonic generator, the amp amplifies or reduces the amplitude of the sound wave generator and transmits it to the transducer, the piezoelectric ceramic in the transducer converts electrical energy into mechanical energy of vibration, the amplitude is about 5-10μm, the amp is connected to the transducer, amplifies the amplitude of the transducer and transmits it to the vibrator, and then the vibrator transmits the vibration to the solution, so that cavitation occurs in the solution, and the slurry and other oligomeric attachments on the surface of the cloth are separated from the cloth under the cavitation, so as to achieve the purpose of desizing the cloth.

[0135] The ultrasonic frequency of the ultrasonic oscillator 10 is between 20-80KHz, and the input power of each set of ultrasonic oscillator 10 is between 2-30KW. Preferably, the ultrasonic frequency of the ultrasonic oscillator 10 is 28KHz, and the power of each vibrator is 50-100 watts. The ultrasonic power is not less than 20KW, and the power density is not less than 3W / L.

[0136] The vibrator can be a plurality of vibration plates, a vibration rod, an energy-concentrating vibration head, or a combination of multiple vibration modes.

[0137] Furthermore, a plurality of ultrasonic vibrators are arranged at the front, rear, left, right and bottom of the washing tank 3, and the vibrators are arranged in sequence at the front, rear, left and right. Preferably, the distance between the vibrator and the cloth is not more than 500 mm, and the distance between two relatively arranged vibrators is not less than 500 mm.

[0138] Furthermore, since the best cavitation temperature of ultrasound in the dye solution is 50-55°C, and the effect of ultrasound during the production process will cause the water temperature to rise, the dyed fabric will take away the solution and also take away some heat, so the temperature in the washing tank 3 is not constant. For this reason, the washing tank 3 can be designed as a double-layer structure, and the temperature of the solution in the washing tank 3 can be adjusted and controlled by a temperature control device connected to the double-layer structure. Preferably, the temperature control device is heated by circulating water or heat transfer oil, and cooled with cooling water to achieve the purpose of effectively controlling the temperature.

[0139] Furthermore, an ozone generator is included. The ozone generator is arranged in the water washing tank 3, or the ozone generator is connected between the first pump and the water washing tank 3 or the water reservoir or the filter or the oil-water separator or the sedimentation tank through a pipeline. The ozone generated by the ozone generator performs ozone treatment on the water and cloth in the water washing tank 3, further decomposes impurities such as slurry or grease, and improves the treatment effect.

[0140] In one example, cloth tension detection and control and / or edge alignment and / or centering devices and / or unfolding devices are arranged between the cloth sending device 1 and the first pressing device 4, between the first pressing device 4 and the entrance of the washing tank 3, between the supporting wheels of each washing tank 3 and the second pressing device 5 at the corresponding position, between the exit of the washing tank 3 and the last first pressing device 4, and between the second pressing device 5 and the first pressing device 4. The cloth is always in a predetermined position in the width direction of the machine through the edge alignment and / or centering devices, and will not deviate, thereby ensuring the consistency of the two layers of cloth at the first pressing device 4 in the width direction, ensuring that the edges of the two layers of cloth can be aligned, ensuring that dry-wet mixed pressing operations or rotation to reduce the liquid content can be performed in the width direction of the entire cloth, so that the liquid content of the two sides of the cloth and the middle part are consistent.

[0141] In one example, an unfolding wheel is provided before the cloth enters the washing tank 3 and before entering the pressing wheel group. The unfolding wheel is an aluminum sheet unfolding wheel or an arc-shaped bending roller or an unfolding wheel with cones at both ends or a spiral roll unfolding wheel, so as to facilitate the cloth to run in an unfolded state;

[0142] In one example, the tension of the cloth at the relevant position is detected by a tension detection device, and then the rotation speed of the corresponding power roller is controlled to achieve the purpose of controlling the tension of the cloth.

[0143] A tension detection and control device is provided in front of or behind one or more supporting wheels or the second pressing device 5, and the tension of the cloth at the relevant position is detected by the tension detection device, and then the rotation speed of the guide wheel or the pressing roller is controlled to achieve the purpose of controlling the tension of the cloth, so as to ensure that the tension of the cloth is constant during operation.

[0144] The tension detection and control device includes but is not limited to a swing-arm angular position potentiometer device or a pressure and tension sensor.

[0145] In one example, in order to minimize the tensile deformation of the cloth due to tension changes during operation, at least one supporting wheel of the upper wheel group 11 and / or the lower wheel group 12 is connected to a power device, and preferably all the supporting wheels are connected to the power of the second pressing device 5 above the washing tank 3 at the corresponding position.

[0146] Furthermore, a reeling device is provided in front of the frame 2, and a heating device and a finished product collecting device are provided behind the frame 2. The heating device is a heating wheel group heating device or a stenter setting machine or a drying box.

[0147] Through the repeated bending and pressing of the supporting wheels and the second pressing devices 5, the slurry or grease carried on the cloth can be accelerated to swell and break, and then separated from the cloth surface, thereby improving the washing efficiency.

[0148] In one example, in order to ensure that the amount of liquid in the width direction of the washed cloth is consistent, at least the third pressing roller 13 and / or the fourth pressing roller 14 at the last second pressing device 5 are adjustable middle and height rollers. By passing hydraulic or air pressure into the interior of the roller, the diameter difference between the middle and both sides of the roller is changed, thereby adjusting the uniformity of the pressing.

[0149] Since the cloth has a better washing effect in a swollen state, and in the subsequent dyeing process, the cloth in a swollen state is easier to dye, in order to improve the washing effect and the dyeing rate, a homemade environmentally friendly swelling agent A is added to the washing tank 3. The addition of the environmentally friendly swelling agent A not only improves the washing efficiency, but also improves the dyeing rate of the dye in the subsequent dyeing process.

[0150] Each second pressing device 5 performs pressing treatment on the cloth while conveying the cloth. After multiple pressings, the slurry or grease carried by the cloth can be easily removed.

[0151] In one example, the water washing machine also includes a heating component, which includes a steam or thermal oil pipe and a heat exchanger. The heat exchanger is connected to the pipe and is arranged inside the water washing tank 3. The water in the water washing tank 3 is heated by steam or thermal oil. Preferably, the heat exchanger is arranged inside between two adjacent water washing tanks 3.

[0152] High temperature can accelerate the decomposition or dissolution of impurities such as slurry or grease carried by the cloth, and the washing efficiency is improved by heating the washing liquid and the cloth in the washing tank 3.

[0153] Of course, under the premise of having a steam boiler, the hot water generated by the boiler can also be directly passed into the washing tank 3 for water washing.

[0154] In one example, the washing machine further includes a water spraying device, the water spraying device includes a first circulating water spraying device, the first circulating water spraying device includes a first front water spraying device or / and a first back water spraying device, a first pipe connected to the first front water spraying device or / and the first back water spraying device, and a first pump connected to the first pipe; the water inlet of the first pump is connected to the washing tank 3 or to the water reservoir or the oil-water separator or the sedimentation tank or the clean water source, the water outlet of the first pump is connected to the water inlet of the first front water spraying device and the first back water spraying device, the water spraying port of the water spraying device is arranged toward the front side or / and the back side of the fabric, and the water spraying port of the water spraying device is arranged below or / and above the liquid surface or / and in front of the second pressure device;

[0155] Optionally, the water washing tank 3 is provided with a water outlet and / or an overflow port, the water inlet of the first pump and / or the second pump is connected to the water outlet and / or the overflow port of the water washing tank 3, or the water inlet of the first pump is connected to a water reservoir or an oil-water separator or a sedimentation tank or a clean water source.

[0156] Furthermore, a pre-drying device, a steaming device and a finished product collecting device are arranged behind the washing machine, and the pre-drying device is a heating wheel group heating device or a stenter setting machine or a drying box.

[0157] Principle and beneficial effects: The washing tank 3 contains dyeing liquid or auxiliary dyeing liquid for degreasing and desizing or various auxiliary dyeing liquids for cleaning cloth. The cloth passes through the supporting wheels in turn in the woven cloth drying-free washing machine, forming a wavy and stacked production process. Based on the above-mentioned setting of different wheel diameters, the two adjacent layers of cloth will not contact each other, and the travel of the cloth in the washing tank 3 is significantly extended in the effective space, thereby improving the utilization rate of the space. While saving space, water is saved, and the time of physical and chemical changes of the dyeing liquid or auxiliary dye in the washing tank 3 is effectively extended, thereby ensuring product quality and improving production efficiency under limited energy and space conditions.

[0158] The washing tank 3 of the present invention contains auxiliary solution for degreasing, desizing, rinsing and alkali reduction, so that the slurry and grease can be fully swollen, and various dyes or auxiliaries have enough time to contact and combine with the cloth. In addition, the arrangement of devices such as a water spray device and an ultrasonic device further improves the treatment effect.

[0159] Furthermore, the ultrasonic waves on the conventional washing equipment can only process a single layer of fabric, while the ultrasonic waves designed in the present invention can oscillate multiple layers of fabric, thus effectively saving equipment and energy consumption.

[0160] Through the coordinated arrangement of the first pressing device 4 and the second pressing device 5, the dry cloth before washing and the wet cloth with a certain amount of liquid are subjected to dry-wet mixing or liquid transfer treatment, and the moisture carried by the treated wet cloth is redistributed, and a part of it is transferred to the untreated dry cloth, thereby reducing the liquid rate of the treated cloth. In addition, the dehydration effect of the vacuum dehydration device 8 and / or the air knife device 9 further reduces the liquid rate, reduces the time and energy consumption of subsequent drying, and makes it possible to directly perform roller dyeing without drying after washing.

[0161] The liquid removal process of the present invention includes liquid removal treatment by the first pressing device 4, the second pressing device 5, the vacuum dehydration device 8 and the air knife device 9, as well as ultrasonic cavitation vibration treatment and plasma etching and heating treatment. The final liquid content of the cloth can be reduced to a minimum, as low as 20%. It is completely possible to directly apply the dye solution without the need for additional pre-drying device after washing, making it possible to continuously carry out pre-drying-free pad dyeing production after washing.

[0162] Continuous dyeing without pre-drying after washing not only saves energy, but also, because during the washing process, under the long-term action of water and auxiliaries, the fabric fibers are swollen to a certain extent, and the fiber structure of the fabric in the swollen state is relatively loose, it is easier for the dye to penetrate deeply into the fiber structure of the fabric and complete the dyeing. The traditional washing-drying-dyeing process obviously does not have this advantage.

[0163] By changing the wrap angle between the cloth between the first guide wheel and the second guide wheel and the second pressing roller, the contact area between the cloth and the second pressing roller is adjusted. Increasing the contact area can transfer more of the solution carried by the second pressing roller to the cloth, which can better reduce the amount of liquid carried.

[0164] At the same time, the present invention sets the first pressing roller and the second pressing roller with an adjustable spacing, that is, the first pressing roller and the second pressing roller may not be in a pressed state, and the cloth between the first pressing roller and the second pressing roller is only covered on the surface of the second pressing roller, and can slide relative to the second pressing roller (commonly known as slipping), so that the running speed of the cloth between the first pressing roller and the second pressing roller is not higher than the traction speed of the first second pressing device 5 in front, and the cloth will not be loosened or accumulated after being output from between the first pressing roller and the second pressing roller to the first second pressing device 5, thereby ensuring normal operation.

[0165] The present invention also provides a method for reducing the amount of liquid, which is applied to the above constant tension washing machine, wherein the first pressing device at least includes a first pressing roller A, a first pressing roller B, a second pressing roller C, and a second pressing roller D which are arranged in sequence, and the cloth is output from the cloth sending device and enters between the first pressing roller B and the second pressing roller C to be pressed for the first time; after being washed in the washing tank, the cloth is output from the second pressing device at the output end, and then enters between the second pressing roller C and the second pressing roller D to be pressed for the second time;

[0166] The first pressing roller A and the second pressing roller D are steel rods or rubber-coated rollers, the first pressing roller B and the second pressing roller C are water-absorbing rollers, the axis of the water-absorbing roller is a steel core shaft, and the outer circle of the axis is covered or sleeved with an elastic water-absorbing layer, and the elastic water-absorbing layer is one or more of Teflon, graphene, aramid, paper, cotton, polyester fiber, and microporous sponge rubber.

[0167] The present invention also provides a continuous dyeing method, which is applied to the above constant tension washing machine and comprises the following steps:

[0168] The dry fabric is output from the fabric sending device and enters between the first pressing roller and the second pressing roller, and the dry fabric is pressed;

[0169] The dry fabric outputted from between the first pressing roller and the second pressing roller enters from the input end of the washing tank, and passes through a plurality of upper wheel groups and a plurality of lower wheel groups in sequence, so as to cross-convey the fabric to be washed in the washing tank;

[0170] The washed cloth is output from the output end of the washing tank and enters the second pressing device at the corresponding position. The cloth output from the second pressing device carries a certain amount of solution.

[0171] The cloth carrying a certain amount of solution enters the first pressing device again and overlaps with the dry cloth entering the first pressing device, and is pressed by the first pressing roller and the second pressing roller to further reduce the amount of liquid, or is transferred by a water suction roller to further reduce the amount of liquid, and then is output from the washing machine;

[0172] The fabrics output from the washing machine enter the dye liquid tank for immersion treatment;

[0173] The cloth output from the dye liquor tank enters between roller X and roller Y to be pressed;

[0174] The fabric pressed between roller X and roller Y enters the color fixing device for color fixing treatment;

[0175] The finished products are collected by the finished product collecting device as finished products.
